Using MAMP and upgrade from 1.4.8b to 1.4.9

Hello,

I don't think that this problem is version related but I'm using an upgrade from 1.4.8b to 1.4.9.

I get an empty browser window when trying to access the admin page of my local version of OpenCart. The files in the htdocs folder are downloaded backup files of my hosted OpenCart. The database name, user, and pw all match. Can anyone tell me why this is happening?

Thanks
